This program lays a foundation for order, exactness, and absolute truth. The daily practice in the student books teaches the recognition and printing of the numerals from 0 to 100, simple addition and subtraction facts, and multiple counting by 1 s, 2 s, 3 s, 4 s, 5 s, and 10 s. Principles of place value, measurement, calendar use, telling time, and money concepts are also introduced."
